Description

Technical Field

[0001] This utility model relates to the field of turbulence generator installation technology, and in particular to a special lifting tool for intermediate turbulence generators. Background Technology

[0002] The tundish turbulence generator is a device installed in the tundish injection zone of a steelmaking reactor. It effectively reduces the flow velocity of molten steel, confines turbulence within it, increases the proportion of laminar flow in other areas of the tundish, and makes the flow of molten steel more stable.

[0003] Because the turbulence generator on the tundish lacks hooks for hoisting equipment, each time the turbulence generator is hoisted, a steel wire structure must be first wrapped around the outside of the turbulence generator to create a hook. This is cumbersome to install and disassemble. Therefore, there is an urgent need to develop a special hoisting tool for the tundish turbulence generator that can be quickly connected and disconnected from the turbulence generator, facilitating hoisting and use, in order to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this utility model is to provide a special lifting tool for tundish turbulence generators to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A special lifting device for an intermediate turbine pump includes a base plate, pull rods, lifting rings, internal clamping mechanisms, and a drive mechanism. A pull rod is fixed at each of the four corners of the base plate, and the upper end of each pull rod is fixed to the lifting ring. Four internal clamping mechanisms are evenly distributed on the lower side of the base plate. A drive mechanism for synchronously rotating the four internal clamping mechanisms is mounted on the base plate. Each internal clamping mechanism includes: a lead screw, a threaded sleeve, an extension rod, a first clamping plate, a diagonal rod, a second clamping plate, a sliding sleeve, a support rod, and a first bevel gear. The lead screw is rotatably connected to the lower side of the base plate, and a threaded sleeve is mounted on the lead screw. The threaded sleeve is fixed to the first clamping plate via two extension rods. The lower side of the lead screw is fixed to the second clamping plate via a diagonal rod. The second clamping plate is located directly below the first clamping plate. A sliding sleeve is fixed to the upper side of the threaded sleeve and is slidably mounted on the support rod. The support rod is fixed to the lower side of the base plate. A first bevel gear is fixed to the end of the lead screw. A power module and a switch button are mounted on the base plate.

[0007] Preferably, the driving mechanism includes a motor and a second bevel gear. The motor is fixed on the base plate, and the second bevel gear is fixed on the output shaft of the motor. The first bevel gear meshes with the second bevel gear.

[0008] Preferably, the power module is electrically connected to the motor via a wire, and the motor is electrically connected to the switch button via a wire.

[0009] Preferably, the base plate, pull rod, and lifting ring are all made of stainless steel.

[0010] The beneficial effects of this utility model are as follows: When using this special lifting tool for intermediate tundish turbulence generators, firstly, the inner clamping mechanism is inserted into the turbulence generator. Then, the motor drives the second bevel gear to rotate, which in turn drives the first bevel gear to rotate. The first bevel gear then drives the lead screw to rotate, which in turn moves the threaded sleeve. The threaded sleeve then moves the first and second clamping plates outwards, causing them to clamp against the inner wall of the turbulence generator. Finally, the hook of the external lifting mechanism is attached to the lifting ring, and the turbulence generator can be lifted. In summary, this utility model allows for quick connection and separation from the turbulence generator, facilitating its lifting and transportation, and is convenient to use.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] See Figures 1-5 In this embodiment of the utility model, a special lifting device for an intermediate tundish turbulence generator includes a base plate 1, pull rods 2, lifting rings 3, inner clamping mechanisms 4, and a drive mechanism 5. A pull rod 2 is fixed at each of the four corners of the base plate 1. The upper end of each pull rod 2 is fixed to a lifting ring 3, which is connected to a hook of an external lifting mechanism. The four pull rods 2 disperse the tension on the base plate 1, improving stability. Four inner clamping mechanisms 4 are evenly distributed on the lower side of the base plate 1. A drive mechanism 5 is installed on the base plate 1 to drive the four inner clamping mechanisms 4 to rotate synchronously. Each inner clamping mechanism 4 includes: a lead screw 401, a threaded sleeve 402, an extension rod 403, a first clamping plate 404, a diagonal rod 405, and a second clamping plate 406. The system comprises two clamping plates 406, a sliding sleeve 407, a support rod 408, and a first bevel gear 409. A lead screw 401 is rotatably connected to the lower side of the base plate 1. A threaded sleeve 402 is mounted on the lead screw 401. The threaded sleeve 402 is fixed to the first clamping plate 404 via two extension rods 403. The lower side of the lead screw 401 is fixed to the second clamping plate 406 via a diagonal rod 405. The second clamping plate 406 is located directly below the first clamping plate 404. A sliding sleeve 407 is fixed to the upper side of the threaded sleeve 402. The sliding sleeve 407 is slidably mounted on the support rod 408, which is fixed to the lower side of the base plate 1. The first bevel gear 409 is fixed to the end of the lead screw 401.

[0021] The drive mechanism 5 includes a motor 501 and a second bevel gear 502. The motor 501 is fixed on the base plate 1, and the second bevel gear 502 is fixed on the output shaft of the motor 501. The first bevel gear 409 meshes with the second bevel gear 502.

[0022] A power module 6 and a switch button 7 are mounted on the base plate 1. The power module 6 is electrically connected to the motor 501 via wires, and the motor 501 is electrically connected to the switch button 7 via wires.

[0023] The base plate 1, the pull rod 2, and the lifting ring 3 are all made of stainless steel, giving them good strength and corrosion resistance.

[0024] Working principle: When using this special lifting tool for intermediate tundish turbulence generator, first insert the inner clamping mechanism 4 into the turbulence generator. Then, the motor 501 drives the second bevel gear 502 to rotate, which in turn drives the first bevel gear 409 to rotate. The first bevel gear 409 drives the lead screw 401 to rotate, which in turn drives the threaded sleeve 402 to move. The threaded sleeve 402 then drives the first clamping plate 404 and the second clamping plate 406 to move outward, so that the first clamping plate 404 and the second clamping plate 406 are clamped against the inner wall of the turbulence generator. Then, the hook of the external lifting mechanism is hung on the lifting ring 3 to lift the turbulence generator.

[0025] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
